Disclosed is a method for performing downlink time difference of arrival (DL-TDoA) by an ultra-wide band (UWB) device that includes selecting at least one active ranging round from a ranging block based on at least one of location information or motion information about the UWB device, transferring, to a UWB sub system, a command including information about the at least one active ranging round, and performing a DL-TDoA operation based on the information about the at least one active ranging round.

An electronic device is provided. The electronic device includes a communication module, a first ultra-wideband (UWB) module, a second UWB module, and a processor operatively connected to the communication module, the first UWB module, and the second UWB module, wherein the processor is configured to determine a direction of a user's gaze, based on data acquired from the first UWB module and data acquired from the second UWB module, select at least one external electronic device positioned in the gaze direction, and send, through the communication module, a request to the selected external electronic device to output media.

Technologies directed to data transfer protocols for Ultra-Wideband (UWB) are described. One method includes a UWB radio of a first device receiving first data from an application. The first device sends data to second and third devices, the data identifying a number of data rounds, a duration of each round, a duration of a data slot, a duration of a data block, and a first slot index for the second device and a second slot index for the third device. The first device sends, during a first slot associated with the first slot index, the first data to the second device using the UWB radio. The first device sends, during a second slot associated with the second slot index, the first data to the third device using the UWB radio.

An electronic device is provided. The electronic device includes an antenna module, a communication module configured to control the antenna module, and at least one processor operatively connected to the communication module, wherein the at least one processor transmits a ultra-wide band (UWB) signal including a first data frame, receives, based on the transmitted first data frame, a reflected first data frame, obtains a first channel impulse response by using the reflected first data frame, acquires information by using the channel impulse response, and receives a UWB signal including a second data frame from an external electronic device in response to the transmitted first data frame.

Provided are an electronic device that performs ranging by using an ultra wide-band (UWB) communication scheme and an operation method of the electronic device. The operation method of the first electronic device includes transmitting a first ranging control message (RCM) comprising interval information to a second electronic device, determining a first time to transmit a second RCM based on the interval information, determining a first RCM timing window (RTW) based on the first time, transmitting the second RCM to the second electronic device in the first RTW, and transmitting a third RCM at a second time in a second RTW, based on a failure to receive a response message corresponding to the second RCM within a specific time period in the first RTW, wherein the second time is a random time point in the second RTW.

A method includes determining one or more active slots and inactive slots in an ultra-wide band (UWB) ranging round. The method also includes determining multiple UWB silent periods in the ranging round based on an arrangement of the inactive slots. The method also includes determining a sleep-wake-up schedule that aligns with at least one selected silent period of the multiple UWB silent periods in the ranging round, the sleep-wake-up schedule to be used for Wi-Fi communication. The method also includes waking up a Wi-Fi station (STA) for the Wi-Fi communication during the at least one selected silent period, then going back to sleep according to the sleep-wake-up schedule.

Systems and methods for alternative payment mechanism payments using ultra-wideband radio technology are disclosed. A method may include a payment terminal computer program executed by a payment terminal selecting a customer electronic device that is conducting the payment transaction with the payment terminal; communicating, via a payment terminal UWB radio to the selected customer electronic device, payment transaction details for the payment transaction comprising a merchant identifier and a transaction amount; receiving, from the selected customer electronic device via the payment terminal UWB radio, an APM payment message for an APM payment provider; communicating the APM payment message to the APM payment provider, wherein the APM payment provider is configured to decision the transaction based on the APM payment message; and receiving, from the APM payment provider, a payment confirmation for the payment transaction.

A method performed by a first ultra-wideband (UWB) device in a wireless communication is provided. The method includes configuring the first UWB device as an advertiser and transmitting a UWB message for advertisement, wherein the UWB message is used for measuring an angle of arrival (AoA).

Examples of techniques for vital train tracking using an ultra-wideband ranging system are disclosed. The system includes a train disposed on a track, the train having at least two onboard UWB beacons configured to broadcast a unique beacon identification number. The system also includes a plurality of wayside UWB beacons disposed along the track, a subset of the plurality of wayside UWB beacons being connected to a wayside communications network, wherein at least two of the plurality of wayside UWB beacons are configured to receive the unique beacon identification number. The system also includes a central computer in communication with the wayside communications network, wherein the central computer is configured to determine a position of the train on the track based at least in part upon known location of the at least two wayside UWB beacons.
